Does it have to know? The task manager doesn't kill tasks that loop
endlessly (in the while(1) {} sense), so why does it have to kill a
task that has disabled signals (by overriding the signal handler), and
loops generating signals?

Of course, SIGKILL mustn't be overridable, as you'd be unable to kill
the task then.
